Panduit FWUYL7575LNM007 OM5 24-Fiber Trunk Cable Assembly
The Panduit FWUYL7575LNM007 QuickNet™ trunk delivers 24 fibers of OM5 wideband multimode capacity in a 7-meter pre-terminated assembly engineered for high-density data center spine-leaf architectures. PanMPO female connectors on both ends support Method B polarity for 40/100GBASE-SR4 bidirectional transmission, while the HD Flex small-diameter design consumes 30-40% less pathway space than traditional trunk cables. Ultra Insertion Loss certification ensures <0.35 dB per connector pair across all 24 fibers. Low Smoke Zero Halogen jacket construction meets international plenum-equivalent fire safety standards for enclosed rack environments and under-floor pathways where PVC off-gassing is prohibited.

OM5 fiber extends traditional OM3/OM4 850 nm transmission windows to include 950 nm short-wave wavelength division multiplexing (SWDM), enabling four-lane 40/100 Gigabit Ethernet over distances up to 150 meters on a single duplex LC or 12-fiber MPO connection. The FWUYL7575LNM007 trunk leverages this extended bandwidth to future-proof spine-to-leaf switch interconnects in preparation for 200G/400G migration paths without infrastructure replacement. Panduit's HD Flex construction reduces cable outer diameter to 3.0 mm per fiber pair through optimized buffer tube geometry and bend-insensitive fiber design (10 mm minimum bend radius), achieving a 30-40% space savings critical when rack-to-rack horizontal pathways are already at 40% fill ratio per NEC Article 770. The Ultra Insertion Loss grade guarantees ≤0.35 dB per mated MPO connector interface—tighter than the industry-standard 0.75 dB TIA limit—preserving optical power budget headroom on multi-tier switched fabric topologies where three or more connector pairs appear in series between active optics.
Method B polarity mapping implements the TIA-568-C.0 standard key-up/key-down pairing strategy: Position 1 on the transmit-end connector maps to Position 12 on the receive end, Position 2 to Position 11, and so forth across all twelve fiber positions in each MPO connector. This direct cross-over eliminates the need for polarity-flip cassettes or gender-changer adapters when connecting 40GBASE-SR4 QSFP+ transceivers (configured as parallel optics with four transmit lanes and four receive lanes). The PanMPO female pinless design provides 500+ mating cycles per TIA-604-5 (FOCIS-5) without ferrule endface damage, and the female-to-female trunk configuration allows direct connection to cassettes, patch panels, or switch modules equipped with male MPO interfaces. Factory testing validates each trunk across all 24 fibers for insertion loss, return loss, and polarity continuity, with serialized test reports providing acceptance documentation for SOC 2 infrastructure audits.
Data center operators deploying leaf-spine Clos fabrics face two infrastructure constraints: pathway congestion at 25–40% fill ratios where traditional 4.8 mm trunk cables trigger NEC derating requirements, and fire marshal restrictions on PVC jacket materials in sub-floor plenums or enclosed vertical shafts. The HD Flex 3.0 mm profile allows installers to route 18–24 trunks per 4-inch ladder rack without exceeding 40% fill, maintaining airflow and simplifying MACs when individual trunks need replacement. The LSZH jacket meets IEC 60332-3-24 Category C flame propagation limits and IEC 61034-2 smoke density <50% light transmittance, satisfying European EN 50575 CPR Cca/B2ca/Dca ratings and U.S. equivalent plenum safety performance for installations where local Authority Having Jurisdiction (AHJ) prohibits PVC off-gassing in occupied or enclosed spaces.
7-meter length bridges typical row-to-row or rack-to-End-of-Row (EOR) switch distances in hot-aisle/cold-aisle layouts without excess service loop, reducing clutter and simplifying as-built documentation. The factory-terminated PanMPO connectors eliminate field fusion splicing or mechanical termination labor—critical when deploying 48-port leaf switches where each uplink requires a 24-fiber trunk (two 12-fiber groups for redundant paths). OM5 backward compatibility with 40GBASE-SR4 and 100GBASE-SR4 optics (850 nm single-wavelength) preserves existing transceiver inventory during migration, while the 950 nm SWDM capability positions the infrastructure for 200GBASE-SR4 (50G per lane × 4 lanes) or 400GBASE-SR8 breakout topologies when next-generation optics arrive. Lime jacket color aligns with TIA-598-D Annex F color coding for instant visual identification during adds/moves/changes, reducing the risk of accidental cross-patching between OM3 (aqua) and OM5 (lime) infrastructure.
The FWUYL7575LNM007 meets ISO/IEC 11801 Edition 2.2 Cabling Standard, TIA-568-C.3 Optical Fiber Cabling Components Standard, TIA-492-AAAD OM5 fiber performance specification, and TIA-604-5 (FOCIS-5) MPO connector interface geometry, ensuring interoperability with multi-vendor active equipment from Cisco, Arista, Juniper, and Mellanox. RoHS compliance (Directive 2011/65/EU + amendments) provides chain-of-custody documentation for federal GSA Schedule contracts or state-level procurement requiring conflict mineral declarations. For integrators managing leaf-spine fabrics in financial services, healthcare HIPAA data centers, or co-location facilities under NEC Article 770 and NFPA 70 enforcement, this trunk delivers the trifecta of high fiber density, verified ultra-low loss, and international fire safety compliance in a single SKU—eliminating the need to juggle separate part numbers for LSZH vs. plenum ratings or compromise on insertion loss headroom to gain pathway space.
